APPARATUS FOR ROLLING PLASTIC MATERIAL.

SPECIFICATION forming part of Letters Patent No. 439,946, dated November 4, 1890.

Application filed May 31, 1890. Serial No. 353,715. (No model.)

Toall whom it may concern.-

Be it known that I, SAMUEL HALLOCK, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Apparatus for Rolling Plastic Material, which improvementis fully set forth in the following specification and accompanying drawings.

My invention consists of means for rolling plastic material into the shape of rods or sticks, finishing the ends thereof, cutting the same into predetermined size, and branding or trade-marking the same, as will be hereinafter set forth and definitely claimed.

The apparatus is more particularly designed for use in rolling licorice into sticks or pieces; but to such material I do not limit the invention.

Figures 1 and 2 represent side elevations of portions of an apparatus for rolling plastic material embodying my invention. Figs. 3, 4, 5, and 6 represent vertical sections of detached parts thereof. Figs. 7 and 8 represent perspective views of detached parts. Figs. 9 and 10 represent side elevations of portions of the apparatus, including the operating mechanism of the roller thereof. Fig. 11 represents a horizontal section thereof. Figs. 12 and 13 represent side elevations of detached portions of the operating mechanism of the roller, the same being on a reduced scale.

Similar letters of reference indicate corre' sponding parts in the several figures.

Referring to the drawings, A designates a frame or casing, within which is the roller 13, whose shaft 0 is mounted on said casing.

D designates a bed having a curved face, between which and the roller is a space to receive the material, the top E of the bed constituting a table for directing said material to said space.

Near the base of the bed on the face thereof are parallel blades F, and at the sides of said bed are segmental plates G, which are provided with slotted ears H, whereby by means of screws J the plates may be laterally adjusted relatively to the desired length of the The'operation is as follows: The material is supplied to the roller and bed, as most clearly seen in Fig. 2, power being suitably imparted to the roller. As the material is carried down between the roller and bed, it is gradually rounded into rod or stick form and then drops from the bed upon the apron K, by which it is conveyed elsewhere. As the material descends, its ends are pressed against the plates G, and thus finished and made uniform, and as the material passes the blades F it is cut into pieces of predetermined length, after which it is impressed against the die K, and thus receives its brand or trade-mark. To the shaft O is secured the cylinder or ring L, within which are located the contacting-pulleys M M, which are connected, respectively, with shafts NN, the latter being mounted on the rocking or swinging arm P, whose axis Q is on the standard A of the casing A, and having a spring R, encircling :or otherwise attached thereto and bearing against the arm P, so as to throw the latter in one direction, in the present case to the left. On the shaft N is a cam S, which is adapted to bear against a pulley T, mounted on the side of the casing A or standard A thereof, it being seen that the tendency of the greatest diameter of said cam is to throw the arm P to the right, whereby the pulley M is brought into contactwith the periphery of the cylinder L, it being noticed that the combined diameters of the pulleys M M are somewhat less than the inner diameter of said cylinder, so that said pulleys have a slight play within the same. The shaft N is provided with a driving-pulley U and receives power in any suitable manner, and as said shaft rotates motion is communicated to the pulley M, and consequently the pulley M, which is in contact therewith. As the cam S rotates and its greater diameter comes in contact with the pulley T, it presses the two pulleys to the right, and forces the pulley M in contact with the cylinder L, thus rotating the shaft 0, and consequently the roller B, in the direction of the arrow, Fig. 13, thus rolling the material down the bedD the greatestportion of the periphery of said roller B. When the narrow diameter of the cam S reaches the roller T, the spring R becomes operative and presses the arm P to the left, carrying the two pulleys with it, and forcing the pulley M in contact with the cylinder L, whereby the motion of the roller B is reversed, and thus the material is carried back or returned up the bed for a certain distance. The cam continues its motion and again causes the reversal of the roller B, whereby the material is carried to a greater extent down the bed, and't-hus the operations continue, so that the material is effectively rolled back and forth until it reaches the bottom of the bed, when it is discharged.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. In an apparatus for rolling plastic material, aroller and acurved bed provided with a series of dividing-knives, said parts being combined substantially as described.

2. In an apparatus for rolling plastic mate rial, a roller and a curved bed provided with adie, said parts being combined substantially as described.

3. In an apparatus for rolling plastic material, a roller and a curved bed provided with knives, and plates for finishing the ends of the material, said parts being combined sub stantially as described.

4. In an apparatus for rolling plastic material, a roller and a curved bed having segmental plates G adjustably secured to said bed, said parts being combined substantially as described.

5. In an apparatus for, rolling plastic material, a roller, in combination with means for imparting motion to the same in reverse direction, the motion in one direction being greater than the other, whereby the material is rolled back and forth on its bed and gradually directed to the discharge end of the bed, substantially in the manner stated.

6. In an apparatus for rolling plastic material, a roller-shaft having a cylinder connected with it, contacting-rollers within said cylinder, either of which is adapted to engage with the same, a rocking arm carrying said rollers, and a spring bearing against said arm, whereby the rollers are successively brought into contact with the cylinder and the roller proper is thereby reversed, so that the'material fed to the bed is rolled back and forth thereon and gradually carried to the discharge end of the same, substantially as described.

7. The roller B, in combination with the cylinder L, connected with the shaft thereof, the contacting-rollers M within the periphery of said cylinder, the rocking arm P, carrying said rollers M M, the roller T on the frame or casing, and aspring bearing against said arm, whereby the latter receives motion in opposite direction and the rollers M are successively brought into contact with the cylinder L, thus reversing the direction of the roller B, substantially as and for the purpose described.
